In H4, yes...
I am not sure of the change made in 2012, but on 2009-2011 the drive mode 'AUTO LSD' was only a 2WD feature and meant TRACtion control but without engine output regulation. In H4, it is (was) called TRAC and is also without any engine regulation, for the most effect. TRAC in H2 has regulation.
In 2012, there may have been an addition in H4 of TRAC (with regulation) and the former unregulated TRAC in H4 is now called AUTO LSD, in H4...?
In either case, the traction control in H4 is on the FRONT and REAR tires, no matter if you call it TRAC or AUTO LSD.
This is why the 4 LO TRAC MOD is so popular for the non Off Road TRD trucks... it provided limited slip to the front tires in L4. Not nearly as firm as A-TRAC, but a world better than just an open front differential in L4.
